Question

describe the activity with labelled diagram to show that magnetic field is generated around a current carrying conductor on the basics of above mentioned activities list the factor on which magnitude of magnetic field produced the point of depend on the earth explanation of dependents

Answer 1

Setup a circuit that posses current and then put a compass beside circuit and when will closed the circuit then you will find deflection in compass

.magnetic field depend on distance its os inversely proportional to the mf and current is directly proportional

Thank you

Answer 2

Explanation:

A current carrying conductor produces a magnetic field around it. The direction of current can be determined by right hand thumb rule. If we curl a finger around a wire, such that the thumb is pointing to direction of current then the magnetic field lines take the direction in which our fingers curl the wire.  $\text { Magnetic field }=\frac{\mu I}{4 \pi r}$.

Where I is the current flowing through the wire and r is the distance of magnetic field from the current carrying conductor, hence "the magnetic field is directly proportional to current and inversely proportional to distance".
